## What this PR does Adds the cozystack-scheduler as an optional system package, vendored from https://github.com/cozystack/cozystack-scheduler. The scheduler extends the default kube-scheduler with SchedulingClass-aware affinity plugins, allowing platform operators to define cluster-wide scheduling constraints via a SchedulingClass CRD. Pods opt in via the `scheduler.cozystack.io/scheduling-class` annotation. The package includes: - Helm chart with RBAC, ConfigMap, Deployment, and CRD - PackageSource definition for the cozystack package system - Optional inclusion in the platform system bundle ### Release note ```release-note [cozystack-scheduler] Add cozystack-scheduler as an optional system package.
